The interference fragmentation function translates the of a quark with transverse projection spin into an azimuthal asymmetry two final-state hadrons. In e+e- annihilation product functions is measured. We report nonzero asymmetries for pairs charge-ordered pi+pi- pairs, which indicate significant in this channel. results are obtained from 672 fb-1 data sample that contains 711 \times 106 and was collected at near ?(4S) resonance, Belle detector KEKB asymmetric-energy collider.

The electromagnetic calorimeter of the BELLE II detector for experiments at Super B-factory SuperKEKB is briefly described. project upgrade to meet severe background conditions expected upgraded KEK B factory presented.
A study of the radiation hardness pure CsI crystals 30 cm long was performed with a uniformly absorbed dose up to 14.3 krad. This initiated by proposed upgrade end cap calorimeter Belle-II detector, using crystals. set 14 truncated pyramid shape used in this produced at Institute for Scintillation Materials NAS from different ingots grown variations growing technology. Interrelationship crystal scintillation characteristics, and technology observed.
